zfs-clone — clone
snapshot of ZFS dataset
See the Clones section of zfsconcepts(7) for details. The target dataset can be located anywhere in the ZFS hierarchy, and is created as the same type as the original.
- Sets the specified property; see
- Creates all the non-existing parent datasets. Datasets created in this manner are automatically mounted according to the mountpoint property inherited from their parent. If the target filesystem or volume already exists, the operation completes successfully.
Example 1: Creating a ZFS Clone
The following command creates a writable file system whose initial contents are the same as pool/home/bob@yesterday.
Example 2: Promoting a ZFS Clone
The following commands illustrate how to test out changes to a file system, and then replace the original file system with the changed one, using clones, clone promotion, and renaming:
createpool/project/production populate /pool/project/production with data #
clonepool/project/production@today pool/project/beta make changes to /pool/project/beta and test them #
renamepool/project/production pool/project/legacy #
renamepool/project/beta pool/project/production once the legacy version is no longer needed, it can be destroyed #
